To your high-calcium diet, add a more festive bone-strengthening option: happy hour! Researchers at Oregon State University have discovered that modest amounts of drinking--linked consistently to better heart health and longer life--seems to improve women's bone density, too. The scientists asked moderate tipplers (meaning they imbibed anywhere from a half to two drinks either daily or near-daily) to abstain entirely for two weeks, and then start up again. Tests showed that bones thinned during the teetotaling, and thickened once the women started hoisting a glass again. But if you prefer not to booze at all, will your bones suffer? No, says Urszula Iwaniec, Ph.D., the study's lead author. "There are many lifestyle factors that have more of an influence on bone health, such as a good diet that includes adequate levels of calcium and vitamin D, and regular moderate physical activity." So feel free to stick to that glass of milk.
